DESCRIPTION

Fiber-reactive dyestuffs, processes for their preparation and their use

The invention is based on the technical field of fiber-reactive dyestuffs.

Dyestuffs which contain a halogen-substituted pyrimidine carboxylic acid amide radical, the dyestuff radical being bonded to the amide group mentioned and also directly to the pyrimidine radical, are known from German Offenlegungsschrift No. 23 14 946, British Patent Application No. 2,103,233 and U.S. Pat. No. 4,118,382. However, these known dyestuffs have deficiencies in their applications properties, in particular in respect of the depth of color achieved in the dyeings and the level of the degrees of fixing in the dyeing processes.

Improved dyestuffs have now been found with the present invention, which correspond to the formula (1) ##STR2## In this formula:

F is the radical of a mono-, dis- or polyazo dyestuff containing sulfo groups, or of a heavy metal complex mono-, dis- or trisazo dyestuff, or of an anthraquinone, phthalocyanine, formazan, azomethine, nitroaryl, dioxazine, phenazine or stilbene dye-stuff;

R^(x) is hydrogen or alkyl having 1 to 4 carbon atoms, such as methyl and ethyl, preferably hydrogen, where --N(R^(x))-- can also be part of a saturated heterocyclic ring;

R^(y) is hydrogen or alkyl having 1 to 4 carbon atoms, R^(z) is hydrogen; such as methyl and ethyl, preferably hydrogen;

Q is phenylene, which can be substituted by 1 or 2 substituents from the group comprising alkyl having 1 to 4 carbon atoms, such as ethyl and, in particular, methyl, alkoxy having 1 to 4 carbon atoms, such as ethoxy and, in particular, methoxy, halogen, such as fluorine, chlorine and bromine, nitro, hydroxy, carboxy and sulfo, the substituents preferably being methyl, methoxy, ethoxy, carboxy and sulfo, or naphthylene, which can be substituted by 1, 2 or 3 sulfo groups and is preferably substituted by 1 or 2 sulfo groups, or Q is alkylene having 1 to 6 carbon atoms, preferably 1 to 4 carbon atoms, such as methylene, 1,2-ethylene or n-propylene, or is alkylene having 2 to 8 carbon atoms, preferably 4 to 8 carbon atoms, which is interrupted by 1 or 2 hetero groups, such as, for example, groups of the formulae --O--, --SO₂ --, --CO--, --NH--, --CO--NH--, --NH--CO--, --SO₂ --NH--, --NH--SO₂ --, --SO₂ -- and --N(R)--, in which R is alkyl having 1 to 4 carbon atoms, such as methyl and ethyl, which can be substituted by hydroxy, sulfato, phosphato, sulfo or acetyloxy, or is propionyl or acetyl, or Q is alkylene-A-phenylene, phenylene-A-alkylene, alkylene-A-phenylene-A-alkylene, phenylene-A-alkylene-phenylene or phenylene-A-phenylene, in which each phenylene, independently of one another, is an optionally substituted phenylene radical described above, each alkylene, independently of one another, is an alkylene radical which is optionally interrupted by 1 or 2 hetero groups, as defined above, and each A, independently of one another, is a direct bond or one of the abovementioned hetero groups;

Preferred dyestuffs of the formula (1) are those in which Q is the phenylene radical and the grouping --Q--(NR^(z))_(z) --Y is bonded to the phenylene radical in the meta- or paraposition to the group --N(R^(Y))--. Of these, those in which R^(x) and R^(y) are both hydrogen and z is the number zero are particularly preferred.

F is preferably the radical of a mono- or disazo dyestuff or the radical of a heavy metal complex azo dyestuff, such as of a 1:2 chromium complex, 1:2 cobalt complex and, in particular, of a o,o'-1:1 copper complex monoazo or disazo dyestuff, or the radical of a triphendioxazine, of an anthraquinone, of a copper formazan or of a phthalocyanine dyestuff, such as of a nickel or, in particular, copper phthalocyanine dyestuff.

If diazo or coupling components which already contain the group of the formula (3) are used as starting substance in the synthesis according to the invention of the azo dyestuffs, the reactions are carried out by the customary procedure of diazotization and coupling reactions, i.e. the diazotization is as a rule carried out a temperature of between -5° C. and +15° C. and at a pH below 2 by means of a strong acid and alkali metal nitrite in a preferably aqueous medium, and the coupling reaction is as a rule carried out at a pH of between 1.5 and 4.5 in the case of a coupling component containing amino groups and at a pH between 3 and 7.5 in the case of a coupling component containing hydroxyl groups, and at a temperature of between 0° and 25° C., likewise preferably in an aqueous medium.

For the synthesis according to the invention of heavy metal complex azo dyestuffs, for example those corresponding to the formula (3j), as a rule those azo compounds which are free from heavy metals and contain a phenolic or naphtholic hydroxy group bonded in the ortho-position or vicinal position relative to the azo group in the coupling component and in which the diazo component radical contains a hydrogen atom or a hydroxy group or a lower alkoxy group, such as a methoxy group, bonded in the ortho-position relative to the azo group are used as starting substances, it being possible for the starting azo compounds which are free from heavy metals furthermore to contain an acylamino radical in bonded form, such as an acetylamino radical. For example, the synthesis of copper complex azo dyestuffs of the formula (4j) can be carried out starting from a starting compound corresponding to the formula (25) ##STR24## in which D₁, K, K¹ and v have one of the abovementioned meanings and are R^(k) is a hydrogen atom or a hydroxy or methoxy group bonded to D₁ in the ortho-position relative to the azo group, and this starting azo compound containing an acylamino group can be reacted with a copper-donating agent, such as a copper salt, analogously to known and customary procedures. If R^(k) is a hydrogen atom or a methoxy group, the compound (25) can be subjected to an oxidative or dealkylating coppering reaction which is to be carried out by the customary route. The copper complex azo compound with the acylamino group now obtained can then be reacted with a compound of the formula (21) or (24) analogously to known procedures, after or with hydrolysis of the acylamino group to the amino group, to give the dyestuff of the formula (1) according to the invention.

The dyestuffs of the formula (1)--called dyestuffs (1) below--are suitable for dyeing and printing the most diverse materials, such as silk, leather, wool, polyamide fibers and polyurethanes, and in particular all types of cellulosic fiber materials. Such fiber materials are, for example, the naturally occurring cellulose fibers, such as cotton, linen and hemp, as well as cellulose and regenerated cellulose. The dyestuffs (1) are also suitable for dyeing or printing fibers which contain hydroxyl groups and are contained in blended fabrics, for example mixtures of cotton with polyester fibers or polyamide fibers.

The dyestuffs (1) can be applied to the fiber material and fixed on the fiber in various ways, in particular in the form of aqueous dyestuff solutions and printing pastes. They are suitable both for the exhaust process and for dyeing by the pad-dyeing process in which the goods are impregnated with aqueous, optionally salt-containing dyestuff solutions and the dyestuff is fixed, after treatment with an alkali or in the presence of an alkali, if appropriate under the action of heat. The dyestuffs according to the invention are particularly suitable for the so-called cold pad-batch process, in which the dyestuff is applied on the padder together with the alkali and is then fixed by storage at room temperature for several hours. After fixing, the dyeings or prints are rinsed thoroughly with cold and hot water, if appropriate with addition of an agent which has a dispersing action and promotes diffusion of the non-fixed portions. These dyeing and printing processes are described in numerous instances in the general technical literature and also in the patent literature, such as, for example, in the publications mentioned at the beginning.

The present invention therefore also relates to the use of the dyestuffs (1) for dyeing (including printing) these materials and to processes for dyeing (and printing) such materials in a procedure which is customary per se, in which a dyestuff (1) is employed as the colorant, by applying the dyestuff (1) to the material in an aqueous medium and fixing it on the material by means of heat or by means of an alkaline compound or by means of both.

If anthraquinone dyestuffs according to the invention display an inadequate solubility in the alkaline dye liquor, this deficiency can be eliminated in the manner known from the literature by addition of dispersing agents or other non-colored compounds, for example a naphthalenesulfonic acid/formaldehyde condensate or, in particular, anthraquinone-2-sulfonic acid.

The dyestuffs (1) are distinguished by a high reactivity, a good fixing capacity and a very good build-up capacity. They can therefore be employed by the exhaust dyeing process at low dyeing temperatures and require only short steaming times in the pad-steam process. The degrees of fixing are high, and the non-fixed portions can easily be washed out, the difference between the degree of exhaustion and degree of fixing being remarkably small, i.e. the soaping loss is very low. The dyestuffs (1) are particularly suitable for printing, above all on cotton, but also for printing nitrogen-containing fibers, for example wool or silk or blended fabrics containing wool or silk.

The dyeings and prints produced with the dyestuffs (1) have, especially on cellulose fiber materials, a good depth of color and a high fiber/dyestuff bond stability both in the acid and in the alkaline range, and furthermore a good fastness to light and very good wet-fastness properties, such as fastnesses to washing, water, seawater, cross-dyeing and perspiration, as well as a good fastness to pleating, fastness to ironing and fastness to rubbing.

The following Examples serve to illustrate the invention. The parts and percentages are by weight, unless stated otherwise. Parts by weight bear the same relation to parts by volume as the kilogram to the liter.

The compounds described by way of their formulae in these Examples are shown in the form of the free acid; they are in general prepared and isolated in the form of their alkali metal salts, such as lithium, sodium or potassium salts, and are used for dyeing in the form of their salts. The starting compounds and components mentioned in the form of the free acid in the following Examples, in particular the Tabular Examples, likewise can be employed in the synthesis as such or in the form of their salts, preferably alkali metal salts.

The absorption maxima (λ_(max)) in the visible range stated for the dyestuffs according to the invention were determined with the aid of their alkali metal salts in aqueous solution. In the Tabular Examples, the λ_(max) values are shown in parentheses against the color shade; the wavelength stated is in nm.

The reaction is carried out at 5° to 10° C., while maintaining a pH of 6.5 by means of 15% strength aqueous sodium carbonate solution.
